That thought had crossed my mind too. When I worked on the rigs I got 
the job of replacing all the batteries in the Bed Head Units every year. 
(A bad job given to me by a small minded boss. Little did he think that 
it gave me carte blanche to order hundreds of AA batteries and the 
opportunity to skive in the accommodation module for days on end. That 
showed me who was boss. :-) )

No problem for me there. :-)

I did not think that it would be a runner. ;)
It takes forever for my printer to start printing after I've sent a page 
over WiFi.

But good to know that the IoT will sometime be a rendering farm.
